Description

A kind of auditory prosthesis

Technical field

The utility model relates to dysaudia deformity therapeutic equipment technical fields, more specifically, it is auxiliary to be related to a kind of tactile The auditory prosthesis and hearing assistance system helped.

Background technique

It is shown according to national Disability Sampling Survey, the existing dysaudia disabled person 27,800,000 in China, wherein adult obstacle is residual Disease people just has 20,000,000 or more, and presbycusis disease incidence may be up to 60% or so, and number is also increasing year by year.However, this The data only to register on the books, actual hearing loss patient numbers are significantly higher than 20,000,000.

Auditory prosthesis, which is one, facilitates dysaudia handicapped person (hereinafter referred to as listening barrier patient) improvement dysacousis, in turn Improve tool, unit and the instrument etc. with his conference communicative competence.It is all in a broad sense sound to be effectively passed to ear Piece various devices can be seen as saying that auditory prosthesis is exactly an electroacoustic amplifier in the narrow sense for auditory prosthesis, passing through it will Sound amplification has heard deaf person originally to can not hear clearly, and the sound that can't hear, this device can be known as auditory prosthesis.

The auditory prosthesis that individual wears mainly has a following four type: boxlike auditory prosthesis, spectacle auditory prosthesis, hard of hearing Formula auditory prosthesis and customized type auditory prosthesis.Boxlike auditory prosthesis can satisfy the need of severe pole severe deafness children and old man It wants, it is more with children and old man user.Spectacle auditory prosthesis, while ametropia and deafness patient needs are able to satisfy, Complete deafness for unilateral ear, another normal or deaf lesser extent person that picks up the ears, can make interconnection of signals by spectacle auditory prosthesis, Its purposes is mainly to aid in the Sound stimulat that monaural deaf as a deer person receives complete deafness side, with sharp safety and dialogue.Behind-the-ear auditory prosthesis, volt After ear, sound hook connects are led made of microphone aperture and a plastic conduit, it is hung over auricle upper limb root, thus hook passes through Flexible plastic tube and ear mold earplug put cavity of concha and external auditory canal opening into, its volt is hidden for hair after ear, are not often outer human hair It is existing, it is able to satisfy the requirement of deaf person's psychology, general utilization rate reaches 60% or so.Customized type auditory prosthesis is " inner ear type hearing aid dress Set ", the general designation of " duct-type auditory prosthesis " and " deep duct-type auditory prosthesis ".The maximum feature of customized type auditory prosthesis is: root Customized, suitable personal ear is removed according to the shape of everyone ear.Wearing is more comfortable in this way, is easier to take and wear.

In addition, the deafness patient overwhelming majority is sensorineural deafness, wherein considerable people, which has, regenerates positive phenomenon: he Difficult is felt to listening to for slight sound, but slightly loud sound is difficult to endure again, that is to say, that the loudness of their tolerances Dynamic range be obviously reduced.Hearing-aid device usually can be achieved at the same time compression and clipping function in amplification.

Audiology is studies have shown that the low frequency part of speech signal contains the first of envelope (envelope) information and vowel Peak value, and high frequency section includes fricative etc., low frequency and high frequency extract the primary auditory cortex and secondary auditory cortex of brain Semanteme be all it is considerable, particularly with listen barrier patient it is even more so.However, the residual hearing of barrier patient is usually listened to concentrate on Low frequency, common hearing aid are difficult to transmit high-frequency information by auditory channel, also difficult even if causing to listen barrier patient's wear hearing aid To understand semanteme.

In order to solve this challenge, the auditory prosthesis of tactile auxiliary becomes the effective workaround in a forward position.Tactile is auxiliary The high frequency section for referring to and effectively being lacked common auditory prosthesis using vibration is helped, brain centres are transmitted to, by brain Pivot fusion tactile and the sense of hearing improve the speech discrimination score for listening barrier patient.But the auditory prosthesis that existing tactile assists at present, Higher speech discrimination score cannot still be reached, the adaptation of auditory prosthesis cannot be still effectively improved according to the source and orientation of sound Ability causes hearing aid effect to be good or bad, and fluctuation is big, and patient is made relatively to be difficult to receive.

Therefore, how to design a high-performance, suitable for all kinds of hearing scenes tactile assist auditory prosthesis, efficiently Merge the technical issues of sense of hearing and tactile are as those skilled in the art's urgent need to resolve.
